Support forces around forever deformed by Globe, can release moment, turning moment only concerned with the bearing angle is independent of the size of the spherical radius of the steel liner plate, so a small rotational torque spherical bearing, spherical ball joint bearing current The angle can be used as more than a two-way sliding seismic 0.06rad steel bearings and ball joints for large rotation of bridge bearings. While rotating the pot bearing pot by deforming the rubber sheet need to adapt the beam angle, the ball bearing due to the rotation of the hinge the impact deformation of the rubber rubber plate diameter, thickness and hardness of the seat is rotated by means that, with the changing the seat angle, change the ball bearing hinge moment is the response, and the thickness of the rubber sheet with certain restrictions, under the conditions of the rubber sheet thickness restricted pot bearing design angle is generally less than 0.02 rad, so the pot bearing rotation range of adaptation and flexibility yuan excluding movable spherical seat bi-seismic steel ball bearing hinge, while the ball bearing hinge to rotate each performance has been, and is more suitable for a wide curved bridge and the bridge occasions. Spherical bearings do not use rubber bearings under pressure so there is no reason to affect the British rubber aging 碧昂 ball bearing hinge rotation function problems, more suitable for use on low-temperature region bridge engineering. Spherical bearings do not use rubber pressure in accordance with national standards for the performance of spherical bearings do a bit of attention to several aspects of the basic requirements. Lower ball bearing hinge basic performance requirements of the role and then vertical design bearing capacity, ball bearing hinge vertical compressive deformation had to be greater than 1% of the total height of seat. Once the ball joint bearing part of the functions of local damage or imperfect situation seismic steel ball bearing hinges, the agent will have a greater impact other functions. Therefore, the use of the whole structure type, need to fully take into account the combination of features and its strength can be sure that the various effects (or load) state functional requirements. Loads structural separation Functional separation method, the ball bearing hinge mainly for vertical and horizontal support functions supporting functions, each essential functional separation. Ball bearing hinges should not normally be a significant difference when the earthquake and wind loads according to the state level can have a ball bearing hinge seismic properties of a variety of functional separation method to separate the entire bridge structure is assumed in the design of the system; the same two-way Transverse Seismic to slip the ball bearing steel hinges, during an earthquake, it may appear on the deformation of the lower structure set up foundations, live in the top of the narrow width of the lower structure, and constitutes only one pivot bearing and bearing damage occurs after the the risk of falling girder bridge, in principle, the use of Class B Supports bi-directional hinge steel ball bearing seismic activity, seismic steel ball bearing hinges, integrity management is provided by the manufacturer Hengshui HaoTong Engineering Rubber Co., Ltd ..
